Parses an enum type and stores the result in value.
If str does not match the nick name of any of the possible values for the enum and is not an integer, FALSE is returned, a warning is issued if warn is TRUE, and a string representing the list of possible values is stored in possible_values. The list is slash-separated, eg. "none/start/middle/end". If failed and possible_values is not NULL, returned string should be freed using g_free().
